My invention relates to typewriting or Wheel 3 is operatively connected to turn with like machines and more particularly to line the platen. as is a finger wheel 4;. The means spacing mechanism therefor. by which the line spacing wheel is operative- Generally stated, the main objects of the 1y connected with the platen may comprise a 5 invention are to produce a line spacing clutch controlled by the finger wheel 4: as so mechanism which is simple in construction, disclosed in the application to Barney 7 13,- highly efficient in use, may be manufactured 199 filed Oct. 13, 1924:. However, for the at comparatively small cost. is easy to assempurpose of the present invention it may be ble, and may be introduced into or detached supposed that the platen, line spacing wheel from the machine as a single unit. and finger wheel a are fixedly connected to 60 To the above and other ends which will turn together. y hereinafter appear, my invention consists in It will be seen that in the present inthe features of construction, arrangements of stance the line spacing wheel an-d the line parts, and combination of devices set forth spacing devices that co-act therewith in the following description and particuarranged outside of the left-hand end plate 70 larly pointed out in the appended claims. 2 of the carriage, and most of suchdevices In the accompanying drawings, wherein are carried by a single bracket or support 5. iike reference characters designate ccrre- This bracket is preferably made of sheet spending parts in the different views: metal and is secured to the left-hand end.

Extending laterally to the platen suitably mounted to travel with and right from the lever 9 is a crank arm 16, best turn in the usual bodily case shiftable carshown in Fig. 1. This arm carries an upriage'of said Remington-noiseless machine, standing post 17 which is fixed to the arm one of the end plates 2 of which carriage 1s and is cyl ndrical in cross sect-ion, for purshown in the drawings. A:" line; spacing poses whichwill presently appear. Extend- 1.

ing through the arm 16 below the post 17, and preferably forming a part of the means by which the latter is secured in place, is a pin 18 that extends below the arm 16. This pin is received in a slot 19 in a sheet metal carrier or slide 20, said slot extending longitudinally fore-and-aft of the machine, or in the general direction of the travel of said pin, a short distance to provide a lost motion connection between the pin and slide, for purposes which will hereinafter appear. The slide 20 is supported on the upper side of the bracket 5 for substantially rectilinear movement fore-and-aft of the machine and constitutes a carrier for a line spacing pawl 21. The slide 20 is guided in its movements in part by a headed screw 22, the stem of which passes through a slot that extends fore-and-att in the slide, the screw being received at its threaded end in a tapped opening in the bracket 5. The lower end of this screw extends beneath the bracket where it receives a'look nut 24. That part of the slide 20 to which the arm 16 of the line spacing lever is operatively connected as described, is in the nature of an arm 20 off-set to the right of the main body port-ion of the slide. This brings the point of lost motion connection 18-19 between the line spacing lever and slide, and also the post 17, in the line of the tore-and-aft operations of the line spacing pawl 21, the slide being guided in its movements by the pin and slot connections 1819 and 22-23.

The line spacing pawl overlies the line spacing wheel 3 and is pivoted near one end at 25 to one side of an upstanding lug 26 formed on the arm 20 of the slide 20. The pivot 25 may be in the nature of a headed screw threaded into a tapped opening in the lug26 and co-acting at its free end portion with a lock nut 27 on the right-hand side of the lug. The heel of the pawl, above its pivot 25, is bored longitudinally of the pawl to receive a plunger or pin 28 normally held pressed against the post 17 by a coiled ex pansion spring 29 contained within the bored opening in which the pin 28 slides. The power of this spring is therefore exerted at all times to turn the engaging nose 21 of the pawl down towards theteeth of the line spacing wheel. It is through the spring 29 that motion is transmitted from the line spacing handle to the line spacin pawl and the slide 20. Positive connection between said parts is not brought about until the pawl has been arrested at the last part of its throw, as will hereinafter appear. In the normal position of the parts the pawl 21 is pressed towards the wheel 3 by the spring 29,

ut engagement with the wheel is prevented by an adjustable line space regulating device or arm 30. This regulating device in the present instance is in. the nature of a guard, guide or shield on which the line spacing pawl normally rests and slides in its line spacing movement,-the extent of such sliding movement of the pawl on the shield determining the extent of line spacing movement transmitted to the platen. This regulating device 30 is made of sheet metal and is pivoted at one end, at 31, to an upstanding lug or bracket arm 32 formed on the bracket 5. It will be seen that this regulating arm is substantially horizontally disposed and extends forwardly t'rom its pivot above the bracket, and in a direction opposite from the direction that the line spacing pawl extends from its pivot and parallel therewith. The pawl has a laterally projecting pin 33 that overlies and rides on the upper inclined cam edge 34 of the regulating arm 30, as best shown in Fig. 5. The pin 33 is pressed down on the cam 34: of the regulating device by the spring 29 of the pawl throughout the stroke of the latter. Therefore, the adjustment of the regulating arm 30 around its pivot 31 determines at what point in the throw. of the pawl it will engage a tooth of the line spacing wheel.

To obtain such an adjustment of the arm 30, and in order to hold it and its co-acting adjusting means against accidental displacement, 1 provide the following means.

It will be seen that the 30 is connected to one end of a contractile spring 35, the other end of said spring being connected to an oft-set ear on a hand-controlled adjusting member or arm 36. This arm is pivoted at its lower end on a headed pivot screw 37 threaded into a tapped opening in a depending arm 38 on the bracket 5, the lett-hand threaded end of the pivot screw 37 co-acting with a lock nut 39. It will be seen that this arm 36 is upright andextends longitudinally lili) at substantially right angles to the length of w the arm 30. A pin e0 projects laterally from the right-hand side of the arm 36 and underlies the arm 30. This pin is adapted to be seated in any one of three locking rel7 cesses or notches 41, 42, or l3 in the bottom edge of the arm 30. It will be seen that these recesses are at different distances from the pivotal center of the member 30, and

thatthe pin is adapted to determine the elevation of said member at any one of three different positions, depending on which of the three notches e1, 42 and 1-3 the pin may be shifted to and seated in. This variation in the elevation of the member 30 determines the point in the throw of the pawl where it will engage a tooth of the line spacing wheel and determines whether each actuation of the handle 9 shall feed the wheel and platen the distance of one, two or three teeth of the wheel.

By reason of the interlocking engagement of the pin 40 in any one of the notches e1, 42 or a3, and the member 30 exerting a downward spring ressu e s stantiall bending against the dead center of the arm 36, the member will act as a spring detent on said arm to hold it against accidental displacement from any one of the three lin'e determining positions to which it may be adjusted by hand. At the same time the member is held against accidental displacement from the position to which it is adjusted by the hand-controlled member 36. ()ppositely disposed depending walls 44 and co-incident with the outer end walls of a terminal recesses 41 and 4-3 respectively, the extreme adjusting movements of nut memler in opposite directions by coacting with the ph in such positions.

r suitable finger piece 46 may be formed on the upper end of the member 36 by the plate from which said member is formed outwardly. On the upper face of this finger piece 46 suitable in dices as 1, 2' and 3 may be provided. llhe corresponding one of these indices registers with the pin 83 in accordance with the adjustment of the member 36 to provide one, two or three teeth spacing.

The pivot 81 of the regulating device is in the nature of a screw threaded into a tapped opening in the bracket arm 32. The outer end ofthis screw receives a lock nut +27, whereas the head 31 of the screw is elongated to extend it to the right into the path of the line spacing pawl and constitutes a stop therefor, as shown in Figs. 1 and 2. From the last mentioned figure it will be understood that under all adjustments of the member 80 the last portion of the stroke of the pawl 21 will bring the upper inclined face or edge 21* thereof against the head or stop 31.

It has been hereinbefore explained that operating motion is transmitted from the handle 9 to the slide 20 and the pawl 21 through the spring 29. When, however, the pawl engages the stop 51 as above explained this will arrest the pawl and slide. but the lost motion connection 18-'19 will permit the handle to receive a continued movement against the plunger 28 and the resistance of its spring 29. This movement will continue a short distance until the plunger is forced, into the bore, as shown in Fig. 2, and the post or pin 17 engages the heel of the pawl 21 above its pivot 25, when further movement of the handle and the parts controlled thereby is arrested. This is the condition of the parts as they appear in Fig. 2, and it results in, at this time, providing a positive train of connections between the line spacing handle and pawl which firmly holds the latter against the stop 31 and in interlocking, engagement with the teeth of the line spacing wheel, to positively prevent overthrow of the latter and the platen; connected'therewith. When pressure on the handle is released by the epand to mamtain the pin 33 pressed down on the device 30, as well as to bring about an effective engagement between the post and pawl at the last part of the SJEOliQ.

By providing a substantially straight inclined supporting edge orsurface 34 on the reglating device 30 for the pawl'to ride on,

lC pawl does not have any change in the e 1011 of its motion until it reaches and igss a tooth of the line spacing wheel. .i here is therefore, every assurance that the pawl will engage the proper tooth of the wheel at all times and underall settings of the regulating device and conditions of use. The construction is such, moreover, that various parts the line spacing mechanism are held against unrestrained loose play at all times under the reaction of springs and there is therefore no unrestrained loosel moving parts to clatter and produce noise as the re sult of any such clatter in the operation of the machine, The operation of the line spacing mechanism is easy and smooth and results in the production of but comparatively little noise. 7

It will be observed that all parts of line spacing mechanism, except the wheel 3 and detent 8, are carried by the bracket 5 and may be introduced therewith or removed from the machine as a single unit; that a sweeping movement of the line spacing handle from left to right is effective by a single operation to line space the platen and return the carriage to the right to begin a new l ne of writing; and that the construction simple, easy to adjust, comparatively inexpensive to manufacture ,and highly efficient in use.

Various changes in the construction mav be made, and parts thereof employed without others, without departing from my invention as it is defined in th accompanying claims.
